As the construction sector in Berlin (Germany) transitions toward stringent carbon-neutral targets mandated by the Gebäudeenergiegesetz (GEG - German Building Energy Act), real estate developers, facade contractors, and architectural procurement specialists are under increasing pressure to source structural fenestration systems that blend ultra-low thermal transmittance ($U_w$ values) with high durability and cost efficiency. Importing wholesale aluminium casement windows directly from certified Chinese OEM/ODM manufacturers has emerged as a high-margin, technically viable solution for major commercial developments, residential Altbau modernizations, and public infrastructure projects across the Berlin-Brandenburg metropolitan region.
Modern Berlin architecture demands a refined balance between heritage aesthetic harmony—frequently seen in urban neighborhoods like Mitte, Prenzlauer Berg, and Charlottenburg—and strict acoustic isolation against high-density traffic noise along major arteries like the Ringbahn and B1 highway. Thermally broken aluminium casement windows engineered in China offer customized frame profile depths (ranging from 65mm to 90mm system depths) with custom powder-coated RAL colors (including popular German choices like RAL 7016 Anthracite Grey and RAL 9005 Jet Black) that perfectly match architectural guidelines while exceeding baseline energy conservation quotas.
Utilizing extruded 6063-T6 alloy aluminum frames integrated with 24mm to 34mm PA66-GF25 polyamide thermal break strips, achieving frame thermal transmittance ($U_f$) as low as $1.2 \text{ W/m}^2\text{K}$ and overall window $U_w \le 0.85 \text{ W/m}^2\text{K}$ when combined with argon-filled triple glazing.
Multi-chamber structural frame design combined with acoustic laminated glass configurations (e.g., 6mm Low-E + 12Ar + 4mm + 12Ar + 6mm Acoustic PVB) delivers noise attenuation up to sound insulation Class 5 ($R_w \ge 45\text{dB}$), critical for Berlin urban residences.
Automated double-head CNC machining guarantees millimetric corner assembly tolerances, corner-crimped structural stability, and full compatibility with European standard tilt-turn, outward casement, and friction stay hardware systems.
Certified Qualicoat Class 2 fluorocarbon (PVDF) and architectural powder coatings provide 25+ years of color retention, corrosion resistance, and salt spray endurance against Europe's seasonal weather shifts.
Every batch undergoes rigorous factory testing in accordance with DIN EN 12207 (Air Permeability Class 4), DIN EN 12208 (Watertightness Class E1050), and DIN EN 12210 (Wind Load Resistance Class C5).
Streamlined containerized export packaging using custom steel-reinforced pallet crates, foam edge protectors, and shrink wrapping, transported directly to Berlin via Hamburg/Bremerhaven ports or the China-Europe Railway Express.

Yes. Our exported thermal break casement window systems are specifically configured to meet or exceed the requirements of the German Gebäudeenergiegesetz (GEG). By utilizing multi-chamber polyamide thermal breaks (PA66-GF25) and argon-filled double or triple Low-E glass units with warm-edge swisspacers, we achieve total window thermal transmittance values ($U_w$) between 0.8 and 1.1 W/m²K, well within German statutory limits.
Every window batch exported from our facility is provided with a complete CE Declaration of Performance (DoP) under EN 14351-1. We supply full factory test reports verifying compliance with air permeability (EN 12207), watertightness (EN 12208), wind resistance (EN 12210), and acoustic insulation (EN ISO 717-1). This guarantees zero friction during German customs clearance at Hamburg port or Berlin dry port logistics terminals.
Absolutely. Our aluminium extrusion profiles are engineered around standard European C-groove and Euro-groove geometries. We regularly assemble windows fitted directly with original German hardware systems (such as Siegenia-Aubi, Roto NT, or GU) inside our factory, or supply the unglazed/unfitted profile frames prepressed for installation of hardware on site in Germany.
Production and shop-drawing approval typically take 20 to 25 days depending on batch volume and custom RAL powder-coating requirements. Ocean freight from our coastal port facilities to Hamburg or Bremerhaven takes approximately 28 to 35 days, followed by 2 to 3 days inland freight directly to site in Berlin. Expedited transport via China-Europe Railway Express (Duisburg/Berlin hub) is also available with a 16-to-20-day transit time.
We employ export-grade heavy packaging protocols. Individual window units are wrapped in 100μm protective film, cushioned with corner plastic guards, separated by foam sheet layers, and secured inside steel-reinforced wooden crates. Crates are equipped with moisture-absorbing desiccant packs and vacuum shrink-wrapped to prevent saltwater air corrosion.
Our technical engineering department generates complete 2D CAD elevation detail drawings, 3D BIM Revit models, and structural wind load calculation sheets tailored to your project blueprints. All technical documentation is prepared in English and German for seamless submittal to local Prüfingenieur (structural inspection engineers) and project consultants.
Operating from an advanced 45,000 m² automated production base, our manufacturing infrastructure houses double-head CNC precision saws, automated corner-crimping presses, and automated glass glazing lines. With over 12 years of specialized architectural window manufacturing and export experience, our technical team works hand-in-hand with main contractors, developers, and trade importers across Europe. From initial shop drawing approval to final container sealing, we guarantee uncompromised quality control, strict dimensional accuracy, and wholesale factory pricing that secures your competitive edge in the Berlin market.
